[mythtv-users] System Hangs

[Simon at the Threshold]

Hi John,

I had a system freeze up on my Athlon XP-2400/Abit KV7 setup, took me a 
long while to work though all of the possible hardware/software options. 
Ended up fixing it with a firmware upgrade to the motherboard.

Still here's a good way of testing your primary hardware...

Monitor your machines temp and check that is working within spec, a CPU 
overheating is a classic way for it to hang. lm_sensors is the way to 
monitor using the onboard sensors). If not you can do it by hand 
(accualy finger) but just make sure before you touch anything on the 
motherboard your grounded by touching the powersupply case.  Gently 
touching the CPU cooler, memory and the southbridge chip should be warn 
but not accualy hot at idle or under load.

Then download and run the correct cpuburn test suite for your CPU and 
check the temp's again.  My athlon idles at PWM(55C) and CPU(47) at top 
whack it stabilises out at PWM(65C) and CPU(55C). The operating specs 
say the safe level is below PWM(85C) and CPU(65C) which sounds high 
enough to boil water IMHO but what the hell if it works.  If your 
tempreture continues to rise (doesn't level out) you have a problem 
(fans, CPU cooler placement etc.).

Download memtest86 and run it (Full test takes 4/5 hours) on your 
machine this will prove your memory is good.

At this point if everything has worked you've should have far confidence 
that the CPU and MEMORY are ok. After this point you'd have to point the 
finger at harder to track down problems. But for the time being try the 
obvious ones noted above.
